The invention relates to a multilevel
power generation system. One end of an insulation box is arranged on the back surface of a vacuum heat collector, clapboards are arranged inside the insulation box, and divide the insulation box into a plurality of mutually independent sealed small space, one end of a
heat pipe is inserted inside the insulation box, the other end of the
heat pipe is connected with a
temperature difference power generation element. Two ends of the
temperature difference power generation element are respectively connected with the
heat pipe or a radiator, the radiator is arranged on the wall surface of a
radiation terminal of the multilevel
temperature difference power generation element,
heat transfer working medium is filled in the sealed small space inside the insulation box, the vacuum heat collector is used for collecting
solar energy, the insulation box and heat conduction oil are used for storing heat, stable
temperature gradient can be provided for the multilevel temperature difference power generation element through the insulation box small space formed by the clapboards, the radiator reduces
cold side temperature of the multilevel temperature difference power generation element through heat
convection, end face temperature difference required in the multilevel temperature difference power generation element is formed, and electrical energy is provided for lamps and lanterns. The multilevel
power generation system has the advantages of being compact in design, simple in installation, free of
mechanical transmission parts, and high in reliability.
